COLLAPSIBLE TUBE.

SPECIFICATION forming part of Letters Patent No. 624,649, dated May 9,1899.

Application filed January 7, 1899.

To all whmn it may concern.-

Be it known that I, WVILLIAM S. SCALES, .of Everett, county ofMiddlesex, State of Massachusetts, have invented an Improvement inCollapsible Tubes, of which the following description, in connectionwith the accompanying drawings, is a specification, like letters on thedrawings representing like parts.

This invention has for its object to improve the construction ofcollapsible tubes; and it consists, essentially, in a collapsibletubular body crimped at one end to fold inward toward the middle of thetube and a head comprising two plates, between which said crimped end ofthe tubular body is clamped. The head will have an opening through it asan outlet, which may be closed by a cap or stopper. As a means ofconnecting said plates together to clamp the end of the tubular bodyflanges may be formed on a neck which will receive said plates betweenthem, and said neck will have a hole through it which will serve as anoutlet for the tube.

Figure 1 shows in vertical section a sufficientportion of a collapsibletube embodying this invention to illustrate the same, the parts being inassembled position but not clamped together; Fig. 2, a similar verticalsection showing the parts clamped together, and Figs.

3 and 4 details showing the crimped end portion of the tubular body.

The collapsible tubular body is herein composed of an inner tube a andan outer tube 1), said tubes being laid one upon the other, although sofar as my invention is concerned said tubular body may be composed ofone or more tubes, as may be desired.

One end of the tubular body, whether composed of one or more tubes, iscrimped for a short distance-i. e., it may be first scored, as at a andthereafter plaited or folded to close inward and partially close the endof the tubular body, and said plaited or folded end portion I hereincall a crimped end.

In Figs. 3 and 4: the end portion of the tubular body is shown ascrimped. The head is composed of two plates 0 and d, preferably madecircular and of any suitable size, and said plates are also preferablymade of metal and dished, and the crimped end portion of the tubularbodyis placed between said plates 0 and cl, as represented in Fig. 1.

A tubular neck 6, preferably made of soft Serial No. 701,491. (Nomodel.)

metal, is provided, which is inserted through central holes formed inthe plates 0 and d, and said neck c has formed at its lower end a flangee, upon which the bottom plate 0 rests, and said neck 6 is also providedwith a shoulder 0 which when compressed by suitable dies provided forthe purpose will project laterally and from a flange which may bepressed down onto or impinged upon the uppermost plate (Z of the pair ofplates, and thereby firmly and securely clamp and hold said pair ofplates together with the crimped end portion of the tubular body betweenthem. The collapsible tubular body will thus be securely and tightlyconnected with the neck.

A closing-cap f will be provided, which is herein shown as provided withan internal screw-thread which is turned onto a screwthreaded portion onthe neck e, although said closing-cap f may be otherwise constructed ora stopper used as a means of closing the tube.

While I have hereinshown the two plates c and d as clamped and heldtogether by flanges on the neck 6, I do not desire to thus limit myinvention, as said plates may be oth erwise connected or clampedtogether, so as to firmly hold the end portion of the tubular bodybetween them.

The crimped end portion of the collapsible tubular body being composedof the same ma;

terial as said collapsible body, will of course,

yield or collapse, notwithstanding it is crimped, unless reinforced orstiffened, and it is desired that they completed collapsible tube shallhave astiffened or unyieldinghead, and consequently the two plates 0andd are made of metal and serve to reinforce or stifien the head of thetube in addition to serving as a clamp for engaging and holding theupper end of the tubular body, and to furthermore insure proper rigidityfor the head one of the two plates, preferably the bottom plate a, willbe made of a diameter approximately equal to the internal diameter ofthe tubular body.

I claim- 1. In a collapsible tube, a collapsible tubular body having acrimped end, a head comprising two plates between which said crimped endis clamped, the bottom plate being approximately the internal diameterof the tubular body and a tubular neck having flanges for holding saidplates securely together, sub- I said plates securely together,substantially as described.

In a collapsible tube, a collapsible tubular body, and a head comprisingvtwo dished plates between which one end of said tubular body isclamped, and a tubular neck having a flange and a compressible shouldere which constitute means for securing said neck to the plates and alsomeans for holding said plates together to clamp and hold the tubularbody, substantially as described.

4. In a collapsible tube, a collapsible tubular body having a crimpedend, and a head comprising two plates between which said crim-ped end ofthe tubular body is clamped, the bottom plate being approximately theinternal diameter of said tubular body, substantially as described.

5. In a collapsible tube, a crimped-top collapsible tubular body, a headcomprising two plates between which said crimped top is clamped whichserves also to reinforce and stiffen said crimped top, to provide anunyielding head for the tube, a tubular neck and means for connectingsaid neck to'the I plates which also holds said plates securelytogether, substantially as described.

6. In a collapsible tube, a crimped-top collapsible tubular bodycomposed of two layers of material laid one upon the other, both layersbeing crimped, a head comprising two plates between which said crimpedend portion of thebody is clamped, and a tubular neck having flanges forsecuring said neck to the plates and also for holding said platesSecurely together to clamp the crimped top of the tube, substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.

WILLIAM S. SCALES.
